The connection terminal is mechanically fixed to the flat conductor cable by caulking the portion. Since the cutting edge of such a cylindrical part directly punches the conductor, a strong contact state is obtained between the outer peripheral surface of the cylindrical part and the cut end of the conductor, so an electrical connection is possible. and can be installed in a mechanically robust manner.
以下、本考案の構成および作用を図に示す実施
例に基づいて具体的に説明する。 Hereinafter, the structure and operation of the present invention will be specifically explained based on embodiments shown in the drawings.

A cutting blade 4 is integrally formed along the opening edge at one end, and the flange portion 3 is formed at the outer peripheral portion of the other end. The flange portion 3 has, for example, a square shape, and its corners are bent in the direction of the cutting edge 4 to integrally form a plurality of, for example, four presser claws 5.

的な接触状態が得られる。 Next, FIG. 5 shows an example in which the connection terminal 1 is attached to a flat conductor cable 6. This conductor cable 6 includes a flat conductor 8 inside an insulating sheath 7. The connection terminal 1 has a cylindrical portion 2
The cutting edge 4 cuts through the insulating coating 7 and the conductor 8 while cutting it. In this state, the cutting edge 4 portion is bent outward by crimping. In this way, the cutting blade 4 and the flange portion 3 in the bent state sandwich the conductor cable 6. Here, the presser claw 5 of the flange portion 3 is connected to the cutting edge 4.
During the crimping process, it penetrates through the insulating coating 7 and the conductor 8 on the front surface and is pressed into contact with the insulating coating 7 on the back surface. In this way, the connection terminal 1 is attached to the conductor cable 6 and electrically connected to the conductor 8 thereof. In such a connected state, the cut portion of the conductor 8 comes into contact with the outer peripheral surface of the cylindrical portion 2 while being subjected to shearing force, so that a reliable electrical contact state can be obtained.

曲げられない。 Next, FIGS. 6 to 8 show the process of attaching the connecting terminal 1 to the conductor cable 6 in relation to the processing machines 10 and 20. First, the connection terminal 1 is placed on a punching machine 10 and a die 11, and is positioned by its protrusion 12. The conductor cable 6 is then placed on the receiver 13. When the punch 14 descends in this state, the receiver 13 and the ring 15 sink against the elasticity of the spring 16, so that the cutting edge 4 of the cylindrical portion 2 is inserted into the center hole of the punch 14.
The cylindrical portion 2 of the connecting terminal 1 passes through the conductor cable 6 while cutting it in order to enter the inside of the conductor cable 8 and apply a shearing force therebetween. Note that at this time, the presser claw 5 enters the groove 17 formed in the punch 14 and penetrates the conductor cable 6, so it cannot be bent.

is placed on top of the die 21 and sandwiched between this and the punch 22. In this case, it is advantageous if the punch 22 is provided with a conical protrusion 23 at the center position, since positioning is reliable and deformation of the cylindrical portion 2 in the diameter reduction direction can be prevented. At this time, two tip portions of the cylindrical portion, that is, the cutting blade 4 and the presser claw 5, are bent outward to sandwich the conductor cable 6. The presser claws 5 sandwich the conductor cable 6 to prevent it from shifting. In this way, the processing machines 10 and 2

For example, it may be in the shape of a hexagonal tube. 6 like this
The rectangular cylindrical portion 2 is punched through the conductor cable 6 and then rotated at an appropriate angle, particularly about 30 degrees, about the center line, so that the apex portion is formed into a conductive part of the conductor cable 6. Since the cut portion of the body 8 is pushed outward, the contact between the cylindrical portion 2 and the conductor 8 becomes even more reliable. Further, in the embodiment described above, the connection terminal 1 is attached to one conductor cable 6, but this connection terminal 1 is used to connect the conductors 8 of two or more conductor cables 6 to each other when they are overlapped. Also used for
本考案では、下記の特有の効果が得られる。 The present invention provides the following unique effects.
筒状部が導体ケーブルの導電体を直接打抜くた

となる。しかも筒状部がその全外周面で導電体に
接触するため、接触面積が大きく、したがつて電
流容量が大きくなり、またその接触部分での接触
抵抗や発熱が小さく抑えられる。 Since the cylindrical part directly punches the conductor of the conductor cable, the contact pressure between the outer periphery of the cylindrical part and the cut end of the conductor is high, and the material deforms to bring them into close contact, thus ensuring reliable contact. The state is obtained. Since the cylindrical portion is caulked in the direction of diameter expansion, the outer periphery of the cylindrical portion and the cut portion of the conductor are brought into a more reliable contact state. Moreover, since the cylindrical part contacts the conductor over its entire outer circumferential surface, the contact area is large, and therefore the current capacity is large, and contact resistance and heat generation at the contact portion are kept small.

つて貫通し、かつ筒状部の先端が折り曲げによつ
てフランジ部とともに、導体ケーブルを挟み込む
ため、接続端子と導体ケーブルとの機械的な結合
が確実であり、外力に対しても、安定化する。 In addition, the cylindrical part penetrates the conductor cable by punching it out, and the tip of the cylindrical part is bent to sandwich the conductor cable together with the flange part, so the mechanical connection between the connection terminal and the conductor cable is improved. is reliable and stable against external forces.

There will be no more sagging. Also, since it is thin overall, it can also be used for floor wiring, etc.
